Re: Clickable table of contents

[Jan-Peter Voigt]

Hello Àlex and Frederico,

the toc-markup is executed/expanded, when the markuplist with 
table-of-contents is created. So \fromproperty #'header:title gets the 
title from the bookpart containing the tocs.
To have a method, that sets the title and the toc item in one step, 
there has to be another way to store title/toc information. One could 
write a scheme-function to create the bookpart, which contains the title 
*and* the \tocItem command.
I use my own functions, to collect music and process books. But it is a 
bit too complex to explain in a few lines here.

Cheers,
Jan-Peter
